I have problems register the plugin.

If you install Mailster you have to validate your purchase code. This ensures you have a valid license and eligible to use Mailster on your site. Here are the error messages which can show up during the verification process.

The Mailster Verification Form

Please enter your Purchase Code!

You need a valid purchase code to activate your license. It’s also called license code or short license. Where’s my purchase code?

Your purchase code is invalid.

To get automatic updates for Mailster you need provide a valid purchase code. Maybe you have entered the purchase code from a different product or you haven’t got one yet. Buy a new one here.

You have to accept the terms of service.

Please enter your email address.

An email address is required to create an account and assign the license.

This purchase code is already assigned to another user!

Each license can be assigned to one user. Please make sure you use the same email address and username you’ve used to sign up. You can manage your current licenses here.

Authentication servers are currently down.

Either our servers we used for authentication or Envatos servers, which are used to verify your purchase are accessible. This is usually a temporary issue so please try again later. If you constantly have problems please open a new ticket.
